What is Crown Lengthening?

Crown lengthening is a dental procedure designed to expose more of the tooth’s surface by removing gum tissue, bone, or both. This treatment is often necessary when there is insufficient tooth structure visible above the gumline, typically for placing a crown or filling. It can also be used for aesthetic purposes, especially to correct a “gummy” smile, where the gums appear to cover a disproportionate amount of the teeth.

Causes of Crown Lengthening

The need for crown lengthening can arise from various dental conditions. Common causes include:

  1. Decay below the gumline: When a tooth’s decay extends beneath the gumline, crown lengthening is required to provide access for treatment.
  2. Fractured teeth: A tooth that is broken near the gumline may require this procedure to allow the placement of a restoration.
  3. Insufficient tooth structure: Sometimes, there is not enough visible tooth structure to support a crown or filling.
  4. Cosmetic reasons: Crown lengthening can be performed to improve the aesthetic appearance of one’s smile by reshaping excessive gum tissue.

Symptoms Indicating Crown Lengthening

Crown lengthening is not always accompanied by symptoms. However, in cases where the procedure is necessary, you may notice:

  • Tooth decay or damage extending below the gumline.
  • Difficulty in placing restorations like crowns due to a lack of tooth exposure.
  • An uneven or “gummy” smile, where too much gum tissue covers the teeth.

Treatment for Crown Lengthening

The procedure is performed under local anaesthesia, where the dentist removes excess gum tissue and may reshape the surrounding bone. Once completed, the tooth becomes more visible, allowing for a proper restoration or aesthetic improvement. The healing period typically lasts a few weeks, and patients are advised to maintain good oral hygiene throughout recovery.

Crown lengthening enhances both the health and appearance of your teeth, offering a long-term solution for dental and cosmetic needs.
